HAMMER.-

SPECIFICATION forming part of Letters Patent No. 624,720, dated May 9,1899.

Application filed June 21, 1897.

To all whom, it may concern.-

Be it known that we, ALEXANDER AHERN and JOHN A. MARTIN, of Rice Lake,in the county of Barron and State of \Visconsin, have invented certainnew and useful Improvements in Hammers; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

Our invention relates to improvements in hammers of that class wherein amagazine is provided for holding tacks or nails and mechanism employedfor successively feeding the same to an eduction-opening in thehammerhead.

The object of our invention is to provide a simple and inexpensiveconstruction of hammer of this character which is adapted to feed thenails or tacks positively and effectually.

\Vith this and other objects in viewthe invention consists in the noveldetails of construction, combinations, and arrangements of partshereinafter more fully described, and specifically pointed out in theappended claims.

In the accompanying drawings, illustrating the invention, Figure 1 is aview in side elevation of the complete tool. Fig. 2 is a horizontalsectional view taken on the line 2 2 of Fig. 1. Fig. 3 is a verticallongitudinal section looking toward the feeding mechanism. Fig. 4 is adetail perspective View of the complete feeding mechanism removed. Fig.5 is an enlarged detail perspective view of the notched feed-plate. Fig.6 is a similar view of the releasing-lever. Fig. 7 is a cross-sectionalView.

Referring now more particularly to the drawings, 1 designates thehammer, which is constructed in the present instance of two sections orside pieces 2 3, the former being provided with a hammer-head 4 and thelatter with a nailclaw 5 at the rear extremity thereof. The tool ispreferably constructed of cast metal suitably hardened, the handle andhammer-head being formed integrally, as-shown.

The tool-handle is provided with a longitudinally-extending passage ormagazine 6 and above the same with guide-flanges 7 on which the tack ornail heads rest, while the shanks Serial No. 641,674 (No model.)

thereof project down into the magazine be low. To afford access to themagazine, the handle may be provided with an opening at the top, closedby a sliding cover 8. The magazine-passage is in communication with avertical feed or discharge passage 9, pro jecting through the lipextremity 10 of the ham mer-head, and adjacent to this passage is arecess 11. sage is of such size as to readily permit the passage of thenails or tacks through its majorportion, but is contracted at the lowerend thereof by beveling the lips 12 13 of the two The said feed ordischarge passections to prevent the tack from dropping out ofengagement with the releasing-lever, as hereinafter described.

In order to force the tacks or nails along the longitudinalmagazine-passage, afollower 14 is provided, which is acted upon by aspi-- ral spring 15. At the point of intersection of the two passages 69 is a feed-plate 16, pivoted in a longitudinal slot 17in the head ofthe section 2. v The outer end of this plate is provided with anattaching projection 18 and on its face or inner side edge withfeed-slots 19 19. The end finger 19 of this feed-plate, formed by theadjacent slot 19, projects out into the magazine-passage 6 and serves asa stop to limit the movement of the tacks or nails. When the notchededge of this plate is moved outward or forward, the first two tacks areengaged and carried forward, the first tack thence being dropped intothe feed or discharge passage 9, while the other tack upon the furthermovement of the feed-plate follows it. Thedischarge of the tacks ornails is regulated by a pivoted releasing-lever 20, which occupies therecess 11. The inner face of this lever, adjoining the passage 9 and atthe lower end thereof,is provided with notches or serrations 21, whichare adapted to receive and confine the tack or nail heads. This serratedend of the releasing-lever normally projects a short distance into thepassage 9, and the beveled or inclined lower inner faces 19 of thehammer-lip sections, before described, are adapted to act in conjunctiontherewith to confine the nail.

thus held can be readily started or penetrated into the object intowhich it is to be driven, and the releasing-lever is then moved torelease the tack-head and permit the tack to be The nail or tack being'driven by the hammer-head 4. As soon as one tack is discharged anothertack is instantly fed into position at the will of the operator, themechanism for accomplishing which will now be described.

The lip-section 13 of the hammer may be pivoted, as shown, to giveaccess to the releasing-lever to release another tack which may becomestuck. This lip is normally held closed by a plate-spring 21. Themechanism for effecting the simultaneous operation of the feed-plate andreleasing-lever comprises a an operating-rod 22, extendinglongitudinallyprojection 18 of the notched feed-plate 16 is,

connected. The forward extremity 29 of this loop-shaped portion of theoperating-rod projects inwardly into the recess 11 and is pivotall yconnected with the upper end of thereleasing-lever 20. By thisconstruction it will be seen that when the finger or thumb piece of theoperating-rod is forced back or moved rearwardly the notched face oredge of the feed-plate will be projected outward to engage the foremosttacks or nails, and the serrated ornotched faces of the releasing-leverwill be moved aside to permit the shank of the said tack or nail toproject out through the discharge-opening in the lip extremity of thehammer-head. A spring 30 is provided to return the operating-rod to itsnormal position as soon as the finger or thumb piece thereof is releasedand to cause the retraction of the notched feed-plate and the outwardmovement of the'serrated or notched faces of the releasing-lever tocause the latter to engage the head of the tack or nail, this operationeffecting the positive movement or feed of the tacks or nails and thepositive engagement therewith of the releasing-lever. When theoperating-rod is moved to effect the further feed, the-tack or nail heldby the releasing-lever is disengaged and may be then driven into thearticle into which it has been started by the hammer-head 4. By thisconstruction a simple and eifective form of tool is provided whichinsures the positive feed of the tacks or nails and is not liable to getout of order.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is I 1. In magazine-hammers, the combinationof a handle having a longitudinal magazinepassage,a hammer-head having avertical discharge-passage in communication with such magazine, a feedmechanism at the junction of the two passages for regulating the feed ofnails to the discharge-passage, consisting of a Vibratory notched plate,and ashouldered releasing-lever the shoulder being above the head of thetack when held by the lever in the discharge-passage to regulate thedischarge of tacks therefrom, and means for simultaneously operating thefeed-plate and release-lever, substantially as described.

2. In a magazine-hammer, the combination of a handle having alongitudinal magazinepassage, a hammer-head having a verticaldischarge-passage communicating therewith, said passage having acontracted outlet and a pivoted releasing-lever provided at its lowerend with notches or serrations adapted to en gage the tack-heads andbear on their upper surfaces, substantially as described.

3. In magazine-hammers,the combination of a handle having a longitudinalmagazinepassage extending therefrom, a hammer-h ead having a verticaldischarge-passage in communication with the magazine, a notched vi-.

bratory feed-plate at the junction of the passages, a releasing-lever inthe discharge-passage provided with serrations or notches adapted toengage the tack-heads and bear on their upper surfaces or tops, andmeans for simultaneously operating the feed-plate and releasing-lever,substantially as described.

In testimony whereof we have signed this specification in the presenceof two subscribing witnesses.-
